Title: Rotary cylinder device
Inventor: YUGI NAOTO
IPC: G11B5/52
Filed: 1992-11-20
Abstract: PURPOSE:To make smaller the difference of a bearing wearing loss in a fluid bearing, which is caused by the difference of temp. and the number of revolution. CONSTITUTION:The fluid bearing is constituted of a shaft 2, a thrust plate 4, a sleeve 4 and a lubricant 5. Electric power generated by a frequency generator 11 is converted into heat by a heating element 14. Controllers 15 and 16 control the connection of the frequency generator 11 to the heating element 14 by the signals of both temp. sensor 12 and a rotation number detecting device 13. Thus, an effect for reducing the bearing wearing loss is specifically large. Electric power generated by the frequency generator 11 only when temp. is low and the number of rotation is high is converted into heat by the heating element 14 so that the temp. of the lubricant 5 is made to increase and the bearing wearing loss is reduced. Then, the bearing wearing loss owing to the difference the temp. and the number of rotation, that is, the difference of motor load current, is reduced. Therefore, the power consumption of VTR is suppressed.

Title: Pwm inverter device
Inventor: NISHIZAWA JUNICHI
IPC: H02M7/48
Filed: 1989-11-30
Abstract: PURPOSE:To reduce the conduction loss of a low pass filter by providing a controller for varying carrier frequency inversely proportionally to the value of an AC output voltage. CONSTITUTION:A controller for varying a carrier frequency is composed of a signal generator 4, a full-wave rectifier 5, a voltage converter 6, a triangular wave generator 7, a voltage comparator 8, etc. The output voltage VS of the generator 4 is converted to a voltage VC and -VC through the rectifier 5 and the converter 6. The generator 7 outputs a triangular wave signal voltage VT proportional to an input voltage + or -VC, generates a signal pulse-width-modulated by the comparator 8, and switches the transistor of an inverter 1. That is, it so operates that, if an AC output voltage V0 is reduced, the carrier frequency is raised. Thus, a harmonic wave current flowing through the inverter 1 and a low pass filter 2 is suppressed.

Title: Picture recorder
Inventor: SATO KAORU
IPC: G03G15/00
Filed: 1988-12-12
Abstract: PURPOSE:To eliminate a jam of paper caused by its position displacement by providing a position alignment control means for delaying an operating speed of a sheet restricting member before it reaches a position alignment position corresponding to sheet size. CONSTITUTION:A position alignment control means controls a pulse motor 6 to be driven moving a movable side plate 2, serving as a sheet restricting member, at a high speed from a home position to a set position. Next, this movable side plate 2 is moved at a low speed from this set position to a resist position (position alignment position corresponding to sheet size). Thus enabling paper to be accurately positioned in a predetermined position, a jam of paper caused by its position displacement can be prevented.

IPC: B23K9/00
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To directly and accurately measure not only an oxygen quantity in inert gas but also nitrogen and other impurities in it. SOLUTION: Inert gas from an inert gas supplying source passes through a selector valve 3, and then it passes through the first opening and closing valve 6 or the second opening and closing valve 7 to be suplied into a welding chamber 8 from a welding torch 9. An impurity content in the inert gas is analyzed by a quadrupole mass spectrometer 13, and an abnormal signal is output to a welding controller when the impurity content exceeds a fixed level. Although an analyzed result therein may be probably different from an actual impurity quantity in the chamber 8 bacause the inert gas introduced into the spectrometer 13 is very small, preliminary measurement by mixing standard gas spotlikely from a standard gas cylinder 16 is carried out to find preliminarily a measuring critical value.

Title: Flow controller
Inventor: SUZUKI TOSHIYUKI
IPC: F15D1/02
Filed: 1988-12-14
Abstract: PURPOSE:To obtain a device of small type and high heat-proof and vibration- proof quality which has characteristics in its flow that the flow coefficient is large in the forward direction and small in the backward direction and accord ingly that it restrains the back flow by providing, inside a pipe, a flow route which gradually reduces its sectional area toward the downstream in forward direction of the flow of the fluid inside the pipe. CONSTITUTION:A nozzle 3 made of a funnel-shaped member is held in such a way as its flat plate part provided around its margin on the upstream in its forward direction A is sandwiched between a pair of flanges 2 of a pipe 1. As it has such flow characteristics that the flow coefficienct is large as the flow route is reduced in the forward direction by forming a smooth flow and it is small in the backward direction as the flow route is suddenly reduced, a great amount of flow flows at the normal time and the back flow is not completely restrained but there is an effect to keep the back flow minimal when the back flow is caused due to the decrease of pressure on the upstream. Additionally, it is possible to set it even at a part of high temperature or at a point of strong vibration as it has no mechanical system, and also it is pos sible to set it where there is not enough space as its size is compact.
